The orange boat seem to not just keep up with the fleet; it was always right near the front. In the racing, it couldn't beat Shortwave because D'Arcy and Linda were just too clever. And as Arthur observed, anytime that Duchess II was in position for a good start, the "jack rabit" would abandon and re-initiate the start sequence! So, what made the orange boat so fast? Was it the original, unscathed, perfectly waxed hull?

Or was it the re-engineered rudder. Look at this NACA 10% foil. It is not just balanced forward of the pivot point. It takes advantage of the hull to eliminate cavitation and aspiration.

You decide!

That is one 'radical rudder'. Does it really make a difference?
What's this about 'an original orange hull'?
Didn't know there was such a colour.

I think part of the speed was also generated by all that "meat" on the rail. You guys really kept the boat flat in the gusts. A couple of hundred pounds of very skillful movable ballast goes a long way.

And . . .

The course wasn't square; port tack was favoured and only the "jack rabbit" could start on port; the start pin got hi-jacked by a serious contender . . .

Just wait 'til next year. The champions will fall! We'll tie a bucket to their keel without them knowing. They will have to race with one hand tied behind their back (my God, what if they beat us again?).

You may not have noticed but the rabbit tacked several times up each windward leg playing the shifts. (It was quite shifty) If you do the math, you'll realize that gaining a few degrees on a well played tack will translate to 10 or 15 boat lengths by time you reach the pin.

Our heavily laden boat sailed the shortest distance. The lesson here is sail the boat and get used to it. You'll be much faster doing this than working on go-fasts. They only give you 10% of the speed. Work on the 90% first; Sail Lots.

Hey Superpiper, at least you didn't get beat by a boat flying only the main

Has Danielle been ok since her racing experience on Paradise?

Sounds like you all had a great time. I need to try to make planns for next year. See if the Valhallabreeze can hold its own in the big race.
